After towing RV with bad batteries, truck blinkers...

... and brake lights doing weird stuff.

Turn signals act like a light is burned out. They blink real fast. Both sides.
Sometimes they blink a little slower, then pick up speed.

If blinker is on, and then you brake also, the blinker freezes up and stops blinking.

If you go behind the vehicle, the turn signal and brake lights can be seen, but are dim.

    And check your FRONT turn signals.
  • clarify all this...
    You say, after. Do you mean after towing and after unhooking and then driving the truck with no trailer then things do this, or it does it when hooked up?
